Abstract

Hybrid buffer layers configurations are investigated for their application in Cu₂ZnSnSe₄ based solar cells. For this purpose, In₂S₃/CdS, ZnS/CdS, CdS/In₂S₃ and CdS/ZnS were deposited by chemical bath deposition and fully characterized. Additionally, the impact of CdS grown with different precursors (CdSO₄ and Cd(NO₃)₂) were also tested. Solar cells with 7.3% efficiency were obtained using In₂S₃/CdS and 8.9% using ZnS/CdS hybrid configurations, with efficiencies comparable or higher than the reference devices. These promising results point towards the need of exploring alternative hybrid buffers for CZTSe-based solar cells not only to maintain high efficiencies, but also to reduce the Cd content.
